Answer to Question #285732 in General Chemistry for gen

Question

1. What is the mass, in grams, of 3.50 x 10-3 mol of aluminum sulfate?

Answer 1

Aluminum sulfate Al₂(SO₄)₃

Step one is finding molar mass of individual elements

Al=2\26.982=53.964

S=3\32.065=96.18

O=12\15.9994=191.988

=342.132gmol^-1

1mol of Al₂(SO₄)₃=342.132g

3.50 x 10^-3of of Al₂(SO₄)₃ =?

Therefore=342.132\ 3.50 x 10^-3

=342.132/0.0035

=1.1975grams
